Minimal change to stop blender window opening across all monitors. Workaround the problem by starting maximized, and using sane defaults for non maximized window. I checked on a few different solutions to this, Using Xinerama works OK, but with different size monitors and not knowing which one the window-manager will pick in advance - this can be wrong too. Now instead of opening with the screen size, just start maximized and use a default size for the non-maximized window (clamped by the screen size). This isn't perfect since you could have 2x monitors at 1024x768, open blender, un-maximize - and blender window would cross over into the second monitor.
